Andrew J. Fabich, Ph.D.

Dr. Andrew J. Fabich is Associate Professor of Biology, Truett McConnell University + Genomics Microbiologist + Guest Author. He grew up in a suburb of Cleveland, OH before moving to Columbus, OH to finish high school and attend Ohio State. After finishing his undergraduate degree, he married his high school sweetheart and began graduate school. His first two children were born during graduate school just before he took a teaching job at Tennessee Temple University. While in Chattanooga, his other 2 children were born before joining the faculty at Liberty University in 2011 where he worked until 2016.  Dr. Fabich has now joined  Truett-McConnell University as an Associate Professor of Biology. His dissertation is on understanding how good and bad E. coli colonize the mammalian intestine to cause disease. He continues working on molecular pathogenesis and colonization of facultative anaerobes in the mammalian intestine.

The goal of Dr. Fabich’s research is to involve undergraduate students to help them better understand the molecular pathogenesis an dissemination of facultative anaerobes in the mouse intestine. They use the streptomycin-treated mouse model of colonization to better understand how commensal (good) E. coli reacts within a diverse intestinal microbial population.
